Within the Madagascar Saturniidae, Bunaea aslauga, the emperor moth, is one of the most attractive and large species. The species is similar to it’s continental relative Bunaea alcinoe (wide spread in central African countries), tough is smaller in size and lighter in color compared to it’s counterpart. Definitely a must for expert breeders but also a fascinating one for less expert one. In this short article we will describe how to approach the rearing of this attractive species from the south of the world
Bunaea aslauga: a tricky species to rear
Bunaea aslauga, the Madagascar emperor moth, has a wingspan of 100-150 mm, making it one of the largest Saturniidae in the island. This species pupates underground and its diapause is linked to the dry season. Warm temperatures and humidity are recommended to let them emerge. Not an easy species to breed, rarely seen as livestock. Definitely a good one for expert breeders which want to embrace new challenges. Hedera helix or Ligustrum sp are very likely going to be accepted by caterpillars. We also suggest having a wide range of alternative hosts to perform a broader test.
The most difficult part in Bunaea aslauga rearing is let the pupae hatch properly. There is still no fixed protocol in order to overcome this issue but general rules can be used. Pupae need to be laid on a wet substrate, they can be totally covered by a thin layer of the same substrate. High temperature is required as high humidity, in order to simulate the Madagascar emperor moth native climate. To further investigate on this subject, the climatic condition of the island will be briefly described in the next paragraph.
Bunaea aslauga: native climate
If you read this article from the northern hemisphere please mind that season are inverted in the country where this beautiful moth is native. This is why we generally offer livestock of this species during the winter of the north hemisphere.
As for any other species, we suggest to check the current weather of Madagascar. It is considered subtropical, with a hot and rainy season starting from November and ending in March. The cooler dry season ranges from May to October (also know as winter). Along the coasts of the island temperatures are consistently higher than in the capital and range from 27°C to 32°C (wet season) and 18°C to 22°C (dry season).
